Select the most appropriate option to fill in blank number 4.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e “occurrence.”
The sentence reads:
“The _______ of landslides can be heightened by human activities, including but not ______ to agriculture and building.”
The word “occurrence” refers to the frequency or rate at which landslides happen.
According to research, human activities significantly increase the probability of landslide occurrence, by disturbing slopes and altering natural stability.
The other options—“name,” “show,” and “form”—do not make logical sense in this context.
